CRAYVALLAC® SL

Micronised polyamide rheology modifier for high temperature process
Contact our experts
Product overview
CRAYVALLAC® SL is a high performance micronised amide wax rheology modifier designed for the high temperature manufacture of moisture curing methoxysilanes systems, where processing temperatures typically lie within the range 90 – 115°C. CRAYVALLAC® SL particles are converted to an interacting network of crystalline fibres. It is this network that gives rise to the shear thinning rheology. This shear thinning characteristic provides for a low viscosity at the shear rates associated with application by extrusion, and a very high viscosity under the low shear rates experienced after application. The net result is ease of application followed by excellent sag and slump resistance.
